JA Extensions manager

[roma10]

Bonjour,

J'ai acheté un template, tout marchait bien jusqu'au jour où l'auteur du template a fait une mise à jour. Depuis, mon slide sur ma page d'accueil ne fonctionne plus. L'auteur a créé une documentation pour mettre à jour le template.

Voici ce qu'il dit:

Upgrading T3 Framework Plug-in

• In the back-end, go to Components menu and click JA Extensions Manager.
• Click the Plug-ins menu item in the left side menu to show the plug-ins installed in your website.
• Search for "T3 Framework" and when found, check the Service to be JoomlArt Updates in the right side column.
• Now click Check update link and wait a few seconds.
• If new version was found, click Upgrade now! link.
• No need to check for code changes, unless the changes affects your customizations. (You can still track code changes after upgrade)
  
  
  Upgrading The Template
  
• In the back-end, go to Components menu and click JA Extensions Manager.
• Click the Templates menu item in the left side menu to show the templates installed in your website.
• Search for "Benz" and when found, check the Service to be Local Service for the template.
• Now click Check update link and wait a few seconds, the extensions manager will tell you there is no new version in the local repository.
• Click Upload now and browse for the latest version of the template.
• Now click Check update link again and then click Upgrade now link. Don't worry, your previous setup will be completely saved into JA Extensions Manager repository. For production websites, I recommend enabling the Offline
• Mode in the Global Configuration (see The Classic Way again) before this step.
• After the upgrade is finished, click Rollback so you can check the files with conflict (changed by both developer and user). A list of files will be displayed and you can click them to check code changes between the latest version and your previous setup including your customizations. This way you can reapply your customizations into the latest version.

J'ai donc installé JA Extensions manager, aucun soucis lors de l'installation. Sauf que lorsque je tente de faire une mise à jour de T3 Framework ou du template BENZ, j'ai ce message: Sorry, no version uploaded in Repository

Du coup, je suis bloqué, rien ne se passe et mon slide est toujours en panne sur ma page d'accueil. Si quelqu'un peut m'aider... Je suis dessus depuis quelques temps maintenant et j'ai trouvé aucune solution...
